HEELHVIACHINE.

forming part of Letters Patent No. 329,022, dated @ctobez 27,1885.Application filed November 26, 1884. Serial No. 148,870. (No model.)

To all whom it may concern:

Be it known that I, FRnDnnIoK W. CoY, of Boston, in the county ofSuffolk and State of Massachusetts, have invented a new and usefulImprovement in Heel-Machines; and I do hereby declare that the followingis a full, clear, and exact description of the'same.

My invention is an improvement in heelmaking machines, and is especiallydesigned as an improvement upon the machine shown in the patent ofEdward H. Parks, granted by the United States Patent Oiiice on the 22dday of April, 188st, and numbered 297,487.

The main part of the invention consists of an'attachment to saidmachine, or to similar machines, for the purpose of inserting pegs ornailsin the heel after it has been formed. Some modifications have alsobeen made in parts of the machine, mainly to conform to the saidattachment.

In the machine shown in the aforesaid patent the lifts of which the heelis made are held together by means of paste applied to each lift afterit has been cut. In working with some kinds of leather it has been foundin practice that the lifts tend to curl or warp, and thereby separate,and it is to obviate this difiiculty occurring when such leather is usedthat the attachment above mentioned is provided. It is designed,therefore, for optional use, and the main machine may be used eitherwith or without it.

The main feature of the invention consists in the combination of apegging or nailing attachment with a heel making machine, in which thelifts are cut and placed together, and the nails or pegs afterwardsinserted when in line with the movement of the dies carried by the tablesupporting the same.

The subordinate features of the invention are also hereinafter explainedand specificall y claimed.

In the accompanying drawings I have shown an attachment adapted toinsert pegs, and have confined the d scription to this form; but it willbe well understood by those skilled in the art to which my inventionappertains that peg-driving and nail driving mechanisms are old andequivalent mechanisms, and I do not limit myself to the particular kindof peg or fastening-pin, since the special peg cutting and feed-.pegging-machine is supported.

ing devices may be exchanged for known devices for feeding nails to thedriving -instrument with the same effect. I have shown only so much ofthe said Parks machine as I deem 5 5 necessary to indicate the place andmanner of attaching the aforesaid lift-fastening devices, and to includethe other modifications hereinafter explained.

In these drawings, Figure 1. is an elevation of the left-hand side ofthe Parks machine, showing the attachment in place and in end view. Fig.21s an elevation of the attachment as seen when looking from the rear ofthe ma chine. Fig. 3 shows in plan a section on line 6 00 cc of Fig. land y y of Fig. 2. Fig. 4 is a view of the front of the attachment, thedie being shown in place upon the bed. Fig. 5is a detailview of thepeg-strip-feed mechanism, the cutting-knife, the driver, and awl, the Vhinged plate being represented as thrown back in order to better showthe feed rolls ordrums, &c. Fig. 6 is a section on line 2 a of Fig. Fig.7 is a section on line 2: o of Fig. 6. Fig.

Fig. 12 is a detail view ofthe mechanism for operating the conveyor-arm. represent details of themechanism for operating the discharge-arm, Fig. 14. being a section online y y, Fig. 13.

In these drawings, A A represent the sides or standards of the machine.Viewed from 8 the rear, (the attachment being on the rear of themachine) Ais the right-hand side piece or standard. To it is bolted abracket, B, provided with a plate or base, b, on which the A stud, 1, 9c(dotted lines of Fig. 2,) is set in this plate and forms the pivot onwhich turns the frame of the pegging mechanism. A slot, 2, Fig. 8, inthe other end of the bracket B, struck on a curve from the stud as acenter, receives a 95 screw, 3, set in the lower face of the frame G,and limits the movement of said frame, while the screw-head prevents anyupward movement of the frame by the concussion of the awl anddriver-bars. The frame 0 is prefer- IOO ably a single casting havingbearings 01 c for the main shaft 3 of the pegging mechanism.

Figs. 13 and 1t v Loose on this shaft is a sprocket-wheel, 4, connectedto the shaft 3 by means of a springclutch, 5, splined to the shaft andpressed into contact with the toothed hub of the wheel 4 by means ofsprings. The sprocket-wheel runs constantly, being driven by means of achain from another sprocket-wheel, 6, on the shaft G of the machine. Theclutch'5 is thrown out of connection with the hub of the sprocketwheelby means of a bell-crank lever, f, pivoted on a stud on the bracket B.The lever has an arm, 7, provided with an incline, 8, adapted to impingeagainst a spur on the rim of the clutch, and thus throw said clutch outof gear with the hub of the sprocket-wheel.

The bell-crank lever is operated from an arm, 9, to which it isconnected by a rod, 10. This arm is on a short shaft, 11, in bearings onthe frame side A, the inner end of the shaft being provided with an arm,12, a frictionroller on the end of which bears against a wheel, 13, onthe shaft '14 of the machine. This wheel 13 is provided with a stud,113, adapted to strike a corresponding stud on the arm 12, and throughthe described connection throw out the leverf, and thus allow clutch 5to come in contact with the sprocket-wheel clutch at the proper momentand start the pegging mechanism, as hereinafter fully explained.

()n the inner end of the shaft 3 is a cam, 15, which acts upon afriction-roller, 71, on an arm, 16, fixed upon the bracket-plate b, sothat when the shaft revolves and the high part 72 of the cambears-against the friction-roller it causes the frame 0 to swinglaterally on its pivoting-stud 1. A spring, 17, on the bracket bearswith its free end against a stud on the frame (J, and causes the frameto return when the high part of the cam has passed the roller on thefixed arm 16. The particular shape of this cam and the precise movementof the frame are hereinafter described fully in connection with themechanism for making the holes and driving the pegs.

In bearings in the frame 0, and above the shaft'3, is a shaft, 19,driven from a pinion, 20, on shaft 3, by an intermediate pinion, 21, inmesh with a pinion, 22, on shaft 19, the gearing being adapted to moveshaft 19 twice as fast as shaft 3. The shaft 19 carries on its inner enda lifting-cam, 23, adapted to catch under a shoulder, 24, on a bar, 25,said bar sliding vertically in guides 26 and 27, and carrying on itslower end the peg-splitting knife 28. A rod, 92, forming an upperprolongation of the bar 25, is in a housing, 30, and is provided with aspring, 31, which throws.

down the bar, forcing the knife to split off a peg from the strip ateach stroke. This bar also carries the driver 45. p

A wheel, 32, on the shaft 19, is provided with a cam-path, 33, intowhich projects a stud from a bar, 34, which carries the awl for piercingthe leather.

On the frame 0 is a short rock-shaft, 35, an upper arm, 73, of which isin contact with a cam, 36, on shaft 19, and the lower end, 74, has apawl, 38, .which moves the feed mechanism for the strip. It is providedwith a spring, 60, for holding the roller to the cam and rocking thepawl. The spring-pawl is supported in a stud on the lower end of thelever and in engagement with a ratchet-wheel. 29, on the upper end of ashaft, 30, which has its upper bearings in a plate, 31, and its lower inthe bracket 9 on the frame 0.

Between the bearings is a pinion, 33, in mesh with pinions 34 and 35 onvertical shafts 36 and 37, which have their bearings in the bracket 9.This bracket is chambered out to receive feed-drums 38 and "39 on theshafts 36 and 37, respectively. I

In the face of the bracket g is a shallow channel, 40, for thepeg-strip, and the feed-drums, which are properly roughened or spurredto take hold of the strip, project a littleoutside the surface or bottomof the channel. The feed-rolls are both turned in the same direction bythe pinion 33, and the parts are so adjusted as to bring the'stripforward at one movement a distance equal to the width of a peg.

ne side of the channel for the pegstrip is made movable, and consists ofabar, 41, an enlarged part of which fits a chamber in the bracket, andis opposite a slot, 42, through which a set-screw, 43, is inserted intothe enlarged part, whereby the bar may be set and held in any desiredposition, so as to prevent the peg-strip from rising from its positionin the channel.

Across the channel for the strip is a path for the knife 28. The part ofthe bracket containing the channel is set-back at an oblique angle tothe part which guides the knife and awl and driving-rods, so that thestrip is split obliquely to properly form the pegs. The strip is held inthe channel by means of a hinged plate, h, which covers the face of thechannel. This plateis provided with a springplate, 46, held by a spring,47, and adjustingscrew 48 against the pegstrip. The hinged plate is heldclosed by means of a pivoted stud and thumb-screw, 55. From thecuttingknife path the channel extends to the path of the driver 45, inwhich path it terminates, and when a peg reaches this path, being forcedalong by the advancing pegstrip and the cut pegs between, it is broughtunder the driver, which, as it descends, forces the peg through a hole,84, in the bottom of the channel and into the heel-blank.

The bracket also is provide ith a guidehole for the awl 49, which isattached to the bar 34, operated by the cam-groove, as hereinbeforeexplained. A second awl may also be set in the bar in line with a secondguidehole, 52, to be used when larger heel-blanks are made. Then the awlis inserted in the holder in line with the second hole, and the cam 15,on shaft 3, is changed for one having higher faces, adapted to throw theframethe space required.

It will be borne in mind that the peg-driving mechanism is in positionon the rear of the machine, so that, when one of the dies is in place atthe front and in process of filling, the other is under the peggingmechanism. The parts are so arranged and timed that as soon as the dieis in place under the pegging mechanism the awl descends and pierces theblank. Then a high part of one side of the cam 15, on themainshaft3,comes,byhalf-revolution,intocontact with the roller on thefixed arm and moves the frame laterally far enough to bring the driverwith the peg in its path directly over the holejust pierced by the awl,and in this position the bar of the driver is dropped by the cam andforced down by the spring to drive the peg while the knife is cuttinganother peg. At the same time the awl descends, by reason of the sh aftmoving twice as fast as the shaft 3,and makes a hole while the peg isdriven in the first. The driver and knife are immediately lifted, andthe frame is moved a step farther by completion of the revolution of cam15, bringing the other and higher part thereofinto contact with theroller of the fixed arm, and the driver and peg are brought to registerwith the peghole last made, and the driver again descends and drives thesecond peg. The highest part of the cam 15 having passed the roller, thespring returns the frame 0 to its original position, and the mechanismis in readiness for a repetition of the operation.

As soon as the operation of pegging is finished the clutch is releasedfrom the drivingwheel on the main shaft,and the pegging mechanismremains quiet until the table has brought another blank around to itsplace.

In order to prevent any accident to the hands of the attendant, I haveraised the die above the surface of the table and provided a collar, m,surrounding the same. The rear of this collar is inclined, as at m, sothat the blank, as it is pushed off, slides down without turning over.

I have also improved the machine shown in the aforesaid patent inrespect to the devices for conveying the blank to the pressingmechanism, and have devised means for holding the blank in accurateposition to be pressed. This part of my invention is shown in Fig. 3.The position of the press is indicated at S and the conveying-arm at T.They retain the relative position which they held in the patent abovereferred to and, with the exception of some immaterial details ofworkmanship, are the same as the devices shown in the said patent, andare operated by similar mechanism.

Secured to the frame A is a bracket, which projects out over and abovethe table and is provided with two arms, which form bearings for thereduced end of a clearingarm, P, which has a depending plate upon itslower surface. This clearer has easy movement in the arms of thebracket, and between the arms a spiral spring is placed, secured at oneend to the bracket and at the other to the journal of the clearer 1?,thus putting a tension upon the said arm and tending to keep it in itsnor mal condition, or return it thereto when, as hereinafter described,it is moved therefrom. A bracket seen red to the press-frame supports avertical shaft, a, to the end of which an arm is secured carrying acompound arm, B, one part of which serves as a guardplate for the outercircumference of the pressplunger, while the other serves to remove theblank from the plunger at the proper time.

After the blank within the die has been nailed, and the table begins itsmovement to the front, the ejector forces out the blank, and when itreaches the clearer 1? the blank is prevented from further movement tothe front as it comes in the path thereof, while the die passes beneathit. If there is any pressure upon the depending plate, the clearer willturn in its hearing until the die has passed entirely from beneath it,when the spring will immediately return it to its normal position. Asthe blank is pushed from the moving die the con veyingarm swings aroundand conveys the blank to the pressing mechanism in accurate positionagainst the guard-flange. The blank is then pressed and the movements ofthe various parts are so timed that as the presspiston descends to itsnormal position the shaft a is given a partial rotation, theguard-flange is moved to the right, and the opposite arm swings acrossthe bed of the press, removing the blanks to a basket or receptacle setto receive them. i

In Fig. 12 I have shown suitable mechanism for operating theconveyerarm. This arm is upon a shaft having its bearings in an offsetof the frame of the machine surrounding the revolving table. This shafthas a gear, 6, secured to it, into which a rack, a, meshes, to move theconveyer-arm over the table in conveying the heel from the die to thepress. The rack is held in place and guided bya part of the shell orcasing of the offset. The end of the rack is rounded or beveled andextended into the space between the table and the surrounding frame, andin this position the conveyer-arm is in its normal position. In themovement of the table a cam, c, or swelling is brought opposite the endof the rack, and in the continued movement of the table the said camforces the rack back, thus operating the conveyer-arm to throw it inwardover the table, as hereinbefore explained. After thecam on the table haspassed this point, a spring, d, on the shaft of the arm retracts thesaid arm and causes the rack to assume its former position.

In Figs. 13 and 14 suitable mechanism is shown for operating thedischarge-arm. The shaft 02 of this arm, as shown in Fig. 13, carries agear upon its end which meshes with a rack, a, moving in suitableguides. This rack has a springprojecticn, p, secured to it, which isstruck by a projection on the arm, which moves the toggle-levers of thepress. This arm derives its motion from a pin set in the face-plate r,secured to' the shaft 9. This shaft is connected by shafts and gears tothe main driving-shaft in theusual way. After the rack has been operatedand the shaft it turned so as to discharge the heel in the press, aspring, 8, on the shaft returns the dischargearm to its normal position.
